为了在供应链协调仿真中体现成员行为特性,提出一种面向主体行为的供应链运作过程集成仿真模型。重点对成员主体结构模型进行了研究,基于该主体结构模型进一步对成员行为进行了详细描述,并对成员行为过程的相关行为协议展开了系统化研究。基于提出的集成仿真模型开发了一个五级供应链运作过程仿真平台,实现了面向供应链成员行为的可视化建模与仿真功能,并通过仿真实验初步验证了所提集成仿真模型的有效性。实验结果表明:面向供应链成员行为的仿真能够通过调整行为协议对供应链运作过程行为策略进行优化,为供应链运作过程的协调建模、协调仿真和协调管理提供一种量化和动态的研究方法。 相似文献

A supply chain is a complex adaptive system that is very difficult to analyze, in particular, with respect to its dynamics, stochastic, and uncertainty. The traditional analytical model is unable to cope with these characteristics of supply chain. In addition, the analytical model may not be solved due to its complexity and nonlinearity. Simulation, especially the multi-agent-based distributed simulation, is one of the most effective tools to model and analyze supply chain. In this paper, a multi-agent platform framework with multi-layers for modeling and distributed simulation of the complex supply chain is presented. In this platform, generic agents for modeling entities in supply chain are described and a novel simulation modeling approach enabled by the platform is proposed. The platform provides a flexible environment for defining, deploying, simulating, and displaying agent-based simulation models and enables users to instantiate generic agents to model their required simulation models rapidly. A three-echelon supply chain model is developed and simulated to illustrate the use of the simulation platform. 相似文献

建立了由多个供应商和多个不确定需求的顾客构成的多阶段供应链动态运作模型。供应链中的供应商可以通过电子市场也可以直接将多种产品供应给不同的顾客。采用已知概率的情景集合描述顾客不确定需求,利用基于情景分析的鲁棒优化方法,建立了供应链的运作模型。该模型为一个多目标动态规划问题,满足诸如尽可能达到顾客需求、系统的总成本最小、供应商的开工率不低于某一指定水平、对应于不确定需求的决策的鲁棒性等多个相互冲突目标。数值仿真结果表明,模型的解是最保守的,但却能够有效地保证供应链运作的鲁棒性。 相似文献

Most of the product life cycle costs and environmental impacts are determined during product design stage. A product supply chain network can be seen as a system dealing with product life cycle processes. Ideally, a product should be designed to have a structure yielding a good life cycle performance in its existing supply chain network. However, there is a lack of research related to modeling supply chain effects in the product design stage. This paper aims at investigating the supply chain effects on product modular design. The life cycle performance of a modular structure (life cycle cost and life cycle environmental impact) at various supply chain states is evaluated by a supply chain evaluation model and analyzed by statistical techniques. The preliminary results indicate that the supply chain-related effects on product life cycle performance are significant and modular structure optimization is effective in reducing the surge of life cycle cost and life cycle environmental impact caused by various supply chain states. The main supply chain effects are identified for use in product design improvement. 相似文献

This paper is geared toward developing an integrated modeling framework and simulation models for understanding decision-making
issues of the supply chain network configuration in an integrated environment.
To achieve this objective, first, this paper presents an integrated modeling framework for multistage supply chains, in which
the interdependencies between model components are captured. Second, the state and resource-based simulation concepts are
used to model the supply chain network configurations. The employment of state and resource-based simulation techniques facilitates
the implementation procedure, since they are strong in modeling dynamic supply chain networks with highly interdependent components
subject to activity start-up conditions. To investigate the impacts of component commonality on integrated supply chain network
performance effectively, a new analytical measure of component commonality that consists of a component-level commonality
index and a product-level commonality index is defined. The results of analysis-of-variance and Tukey’s tests reveal that
there is a significant difference in performance measures, such as delivery time and order fill rates, when comparing an integrated
supply chain with higher component commonality to an integrated supply chain with lower component commonality. 相似文献
